Near a big spring, 9 miles northeast of 'Lincoln Centre' (KUVP 1331 locality) (Cretaceous to of the United States)

Where: Lincoln County County, Kansas (39.2° N, 98.1° W: paleocoordinates 38.6° N, 61.9° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Middle Cenomanian to Middle Cenomanian (99.6 - 89.3 Ma)

• The geologic map of Berry (1952) depicts exposures of the Carlile Shale and lower horizons in this area. Uncrushed preservation (lack of compaction) suggest burial in a bioturbated chalky limestone unit, which tend to produce more three-dimensional specimens. Thus the specimen likely cocured in limestone beds of the Greenhorn Limestone or the Fairport Chalk, and is Middle Cenomanian to Middle Turonian in age" (Schumacher & Everhart 2005 p. 47).
